11. I used this configuration to test the USB hub class. I did this
testing with the following changes to the configuration (in addition
to those listed above for base USB host/mass storage class support):
Drivers -> USB Host Driver Support
CONFIG_USBHOST_HUB=y : Enable the hub class
CONFIG_USBHOST_ASYNCH=y : Asynchonous I/O supported needed for hubs
System Type -> USB host configuration
To be determined
RTOS Features -> Work Queue Support
CONFIG_SCHED_LPWORK=y : Low priority queue support is needed
CONFIG_SCHED_LPNTHREADS=1
CONFIG_SCHED_LPWORKSTACKSIZE=1024
NOTES:
1. It is necessary to perform work on the low-priority work queue
(vs. the high priority work queue) because deferred hub-related
work requires some delays and waiting that is not appropriate on
the high priority work queue.
2. Stack usage make increase when USB hub support is enabled because
the nesting depth of certain USB host class logic can increase.
